An 18-year-old man has been charged with the murder of 17-year-old schoolgirl Lainie Williams, who was stabbed to death in her bedroom in Cefn Fforest, near Blackwood, South Wales. Cameron Cheng, a British national and former boyfriend of Lainie, was also charged with the attempted murder of a 38-year-old woman, believed to be Lainie's mother, Rhian Stephens.
The attack occurred shortly after 7am on Thursday, November 13, 2025, at the family home on Wheatley Place. Armed police and an air ambulance were called, but Lainie was pronounced dead at the scene. Her mother, Rhian, was taken to hospital with serious injuries but has since been discharged.
Relatives reported that the attacker first stabbed Ms Stephens before entering Lainie's bedroom, where she was sleeping. The college student, who was looking forward to her 18th birthday, fought back but succumbed to her injuries.
Cheng has also been charged with possession of a bladed article in a public place. He remains in custody and is due to appear before Newport Magistrates' Court on Monday, November 17.
In tributes, Lainie's family described her as 'so loved,' with her cousin Megan writing: 'Rest peacefully our brave and beautiful cousin Lainie.' A GoFundMe campaign has been set up to cover funeral costs.
Assistant Chief Constable Vicki Townsend urged the public to be mindful of online comments that could affect the investigation, which continues with officers remaining in the area.
